*Man- IMPROVENIENT IN SLATEFRAME$ The Schedule referred to in theseLetters Patent and making part of the same.

To all whom it may concern Be it known tlxat'l, EBENEZERBUTLER, ofSalina, county of Onondaga, State of New York, have invented anew anduseful Improvement in Slate-Frames; and' IV do hereby declare that thefollowing is a vfull, clear., and exact description thereof, which willenable those skilled in the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecification.

This invention consists in forming from the slatefr'ame itseland on itsouter part, bars or rails, capable and for the purpose of being wound orcovered with list', cloth, oi' other proper material, by means of whichthe application of said material to the slateframe is more neatly madeand the cornersl and edges ofV the frame more completely protected thanheretofore.

In accompanying drawlngs- D D is an lordinary school-slate frame, ineach section` of which, by means of a circular saw o1' otherwise, I makea slot, at proper distance from the edge, nearly from end to end,leaving` only sufcient roorn to preserve the strength of the corners orjoints c f the frame.

By 'this means I form, from said section, and consequently, when theframe is together, from the frame itself, and on its outer part, bars orrails, as shown at S S, and that are capable of being used in manner ashereinbefore specified.

These frames are manufactured and sold without the list or covering,that heilig applied by and to suit the taste of nal purchaser.

I disclaim the application of 4list or like material to frame of a slatein any manner or for any purpose whatever, the same having been incommon use for many yearsw V I disclaim slots in a slate-frame unlessextending nearly the entire length of the sections of said frame," andused for the purpose of creating hars or rails on said sections. What Ido claim as new and my invention, and for which I desire to secureLetters Patent, is

A slate-trame, upon the outer side of each sec-tion ot' which is formed,by any means, a rail or bar,for the purpose h'ercinbefore specified. l
